Understanding the classification of fire equipment is fundamental to proper design of safety systems. The question of which type of fire equipment belongs to fire pumping station PNS 110, requires a detailed analysis of regulatory documentation. This is not just a set of pumps, but a complex engineering structure that provides water supply under the required pressure.
The answer lies in the functional purpose of the equipment. According to current standards, this device is classified as stationary fire equipment. It is designed to automatically maintain pressure in the fire-fighting water supply of buildings and structures. Without such equipment, the functioning of modern fire extinguishing systems in high-rise buildings and industrial complexes is impossible.
It is important to note that PNS 110 belongs to the class pumping units special purpose. Unlike mobile fire trucks, this equipment is fixed to the site and operates in automatic or semi-automatic mode. Its main task is to instantly respond to a drop in pressure in the system and supply the calculated volume of fire extinguishing agent.
Classification of fire fighting equipment according to GOST and purpose of PNS
To determine the place of PNS 110 in the general nomenclature, you must refer to GOST R 53280.1-2009. This standard clearly regulates the requirements for automatic fire extinguishing installations. The pumping station here acts as the heart of the entire system, ensuring hydraulic stability.
Equipment is divided into several main groups: basic, special and auxiliary. PNS 110 refers to the main fire extinguishing means at facilities, as it directly supplies water to sprinklers or hydrants. It is not auxiliary, since without it the system will not perform its function.
There is also a division based on drive type and design. In this case, we are talking about electrified installations with diesel backup. This ensures reliability even when external power supply is cut off. Classification implies strict compliance with technical regulations.
⚠️ Attention: Incorrect classification of equipment during design may lead to refusal to accept the facility by supervisory authorities. Always check the compliance of the PNS markings with the design solutions.
Particular attention should be paid to the fact that PNS 110 is permanent installation. It is not intended for transportation to the site of a fire, unlike firefighting motor pumps or tank trucks. Her “workplace” is a specially equipped pump room.
Technical characteristics and design features
When analyzing what type of technology the equipment belongs to, you cannot ignore it technical parameters. The number “110” in the model name often indicates the nominal diameter of the pipes or the capacity in liters per second, which is typical for medium and high power equipment. This determines its performance class.
Structurally, the station is a frame on which working pumps, a jockey pump (to maintain pressure), shut-off valves and a control system are mounted. All elements are combined into a single technological cycle. Automation process is a key feature of this type of technology.
Execution materials must meet the requirements of corrosion resistance. The most commonly used steel is anti-corrosion coated or stainless steel. This guarantees a long service life even in conditions of high humidity in the pump room.
When choosing PNS 110, pay attention to the energy efficiency class of the electric motors used, since the pumps operate in standby mode constantly, consuming energy to maintain pressure.
The control system (control cabinet) refers to electrical equipment first class of complexity. It monitors pressure, bearing temperature, vibration levels and automatically switches pumps when necessary. This makes PNS 110 an intelligent fire safety unit.
Scope of application: where PNS 110 is installed
The scope of application of this technology directly depends on its performance. PNS 110 is designed for facilities with high water consumption. These include multi-storey residential complexes, shopping and entertainment centers, warehouse terminals and industrial enterprises.
In high-rise buildings, the pressure of the city network is not enough to lift water to the upper floors. Here PNS 110 acts as booster station. It provides the necessary pressure for the operation of sprinkler systems and internal fire hydrants.
At industrial facilities where fires of classes A and B are possible, such a station provides a large volume of water in a short time. This is critical for containing the fire before fire crews arrive.
| Parameter | Meaning/Description | Unit of measurement |
|---|---|---|
| Performance | Up to 110 (or according to the passport) | l/s or m³/h |
| Pressure | Depends on building height | m water Art. |
| Pump type | Centrifugal cantilever | - |
| Protection class | IP54 and higher | - |
Features of installation in seismic areas
In areas with increased seismic activity, PNS 110 must be installed on special vibration-proof foundations, and the pipelines must be equipped with flexible inserts.
Regulatory and Certification
Any fire fighting equipment, including PNS 110, is subject to mandatory certification. In Russia, this is regulated by Federal Law No. 123-FZ “Technical Regulations on Fire Safety Requirements”. Without a certificate of conformity, operation of the equipment is prohibited.
The manufacturer must provide a passport, instruction manual and certificate of conformity. The documents must indicate fire hazard class and operating conditions. Checking these documents is the first stage of object acceptance.
The regulatory framework also includes requirements for maintenance intervals. The PNS should be checked monthly and quarterly. The results of the checks are recorded in the log book.
⚠️ Attention: The absence of a valid certificate of conformity for PNS 110 is a gross violation and entails administrative liability for the building owner.
It is important to monitor updates in legislation. Regulations change, and equipment manufactured several years ago may not meet new energy efficiency or noise requirements.
☑️ Checking PNS documentation
Operating principle and automation
The operating principle of PNS 110 is based on the compensation method. Pressure sensors installed in the network transmit a signal to control cabinet. When a fire hydrant is opened or a sprinkler is activated, the pressure drops.
The automation system analyzes the rate of pressure drop. If the leak is small (pumping), the jockey pump turns on. If the fall is sudden (fire), the main operating pumps are started. This allows you to save the resource of the main equipment.
Automatic mode is basic. However, it is possible to manually start from the control panel in the pump room, as well as remote start from the fire station button. This multi-level control system increases reliability.
Modern stations are equipped with telemetry systems. They can transmit data on the status of equipment to the dispatcher’s console or even to the smartphone of the person in charge. This allows you to quickly respond to faults.
Maintenance and diagnostics
The durability of PNS 110 depends on the quality of service. Regular diagnostics Allows you to identify worn seals, bearings or electrical contacts before they lead to system failure.
Every month it is necessary to rotate the pump shafts (if they were not working), check the oil level in the crankcases and the absence of leaks. Once every six months, the pumps are fully commissioned into operating mode with water being discharged.
Particular attention should be paid to the condition of the check valves. Their jamming can lead to water hammer when starting the pump, which is dangerous for pipelines. Visual inspection and listening to the operation of the valves is a mandatory procedure.
Regular maintenance of the PNS 110 reduces the risk of system failure at a critical moment by 85% and extends the service life of the equipment by 1.5-2 times.
Filters on the suction pipes should be replaced when they become dirty. The entry of solid particles into the impeller of a centrifugal pump can lead to its rapid destruction and costly repairs.
Frequently asked questions (FAQ)
Is it possible to use PNS 110 for domestic and drinking water supply?
Absolutely not. Firefighting equipment and systems must be separate. Water in fire tanks may stagnate, and the materials of PNS units may not meet sanitary standards for drinking water. In addition, this violates the principle of a guaranteed supply of water for firefighting.
What is the frequency of oil changes in PNS pumps?
The initial oil change is performed after break-in (usually after 500 operating hours). Further - according to the manufacturer’s regulations, but at least once a year. The quality of the oil is checked visually and laboratory at each maintenance.
What to do if PNS 110 does not start automatically?
It is necessary to immediately switch the system to manual mode and start the pumps with the button. At the same time, call the service department to diagnose the control cabinet and pressure sensors. Operation of a facility with faulty PNS automation is prohibited.
Is a license from the Ministry of Emergency Situations required to service PNS 110?
To carry out maintenance of fire water supply systems and pumping stations, the organization must have a license from the Ministry of Emergency Situations of the Russian Federation for this type of activity. Independent maintenance by facility personnel is permitted only to the extent of daily visual inspection, if this is specified in the instructions.
